INTRODUCTION

This International Standard is one of a series that deals with heat-shrinkable moulded shapes for
electrical purposes.
The series consists of three parts:
Part 1: Definitions and general requirements (IEC 62329-1)
Part 2: Methods of test (IEC 62329-2)
Part 3: Specification requirements for shape dimensions, material requirements and compatibility
performance (IEC 62329-3)
This standard gives one of the sheets comprising Part 3 as follows:
Sheet 102: Heat-shrinkable elastomeric moulded shapes, semi-rigid, material requirements and
system performance
NOTE

See IEC 62329-3-100 for moulded shape dimensions.

material requirements and system performance

1

Scope

This sheet of IEC 62329-3 gives the requirements for heat-shrinkable elastomeric moulded shape,
semi-rigid material requirements and system performance.
Experience of product performance indicates that this moulded shape material is suitable for
inclusion in systems for operation in the following temperature ranges: –75 °C to + 120 °C.
The moulded shapes may be supplied with a pre-coated adhesive. Refer to the
manufacturers/suppliers for options. A guide to adhesive compatibility is given in Annex A.
These moulded shapes are normally supplied in the styles and dimensions given in IEC 62329-3100. The colour is normally Black.
Styles and dimensions other than those specifically listed in IEC 62329-3-100 may be available as
custom items. These items shall be considered to comply with this standard if they comply with the
property requirements listed in Table 1 with the exception of dimensions.
Materials that conform to this specification meet established levels of performance. However, the
selection of a material by a user for a specific application should be based on the actual
requirements necessary for adequate performance in that application and not based on this
specification alone.

Conditions of test for the moulded shapes

The moulded shapes shall be shrunk in a forced air circulation oven for (10 ± 1) min at the
temperature specified in Table 1.

5

Requirements

In addition to the general requirements given in IEC 62329-1, the heat-shrinkable moulded shapes
shall comply with the requirements in IEC 62329-3-100 and Table 1.

6

Moulded shapes material conformance

Conformance with the requirements of this specification shall be based on the results form test
sheets, ( 2 ± 0,15 ) mm thick, unless otherwise specified 1, which shall be prepared from the same
cross-linked heat shrinkable material that is used to manufacture the heat shrinkable moulded
shapes.

7

Moulded shapes compatibility

Conformance with the compatibility requirements of this specification shall be based on the results
from the assembly configuration as shown in Figure 3 of IEC 62329-2.
